Langdon, who won last season’s NHRA Top Fuel championship, earned his third No. 1 qualifying spot of the season and 16th of his career with a stout 3.745-second effort at 325.22 mph Saturday, knocking Doug Kalitta off Friday’s provisional pole.

Langdon is looking for his second win of the season Sunday. He starts his quest in the opening round vs. Terry McMillen.

“Tonight, we felt like we could lay down and try to make the best run possible,” Langdon said in an NHRA media release. “I have a lot of confidence. The last couple races we’ve struggled in qualifying. We feel like we have that little bit of a handle back on the race car again.”

Kalitta didn’t make it easy for Langdon, begrudgingly giving up the top spot despite an outstanding run of 3.746 seconds at 327.82 mph. He’ll face rookie Richie Crampton in Sunday’s first round, while last week’s winner at Joliet, Illinois, Antron Brown will start third (3.763 seconds at 323.04 mph) against Clay Millican.

In Funny Car, Worsham held on to Friday’s provisional pole (4.000 seconds at 321.88 mph), the 16th of his career. He’ll meet Jeff Diehl in Sunday’s opening round.

“The DHL Toyota Camry made a beautiful run down the track,” Worsham said of Friday’s run. “When you can outrun guys like John Force and Tommy Johnson, that says something.”

Speaking of John Force, the 16-time Funny Car world champ is the No. 2 qualifier (4.016 seconds at 322.04 mph). Johnson was No. 3 qualifier (4.030 seconds at 319.67 mph).

“You can’t take anyone lightly,” Worsham said. “I think if I take a first round win tomorrow that’ll be great.”

In Pro Stock, Enders-Stevens continued her red-hot season. Not only does she have a commanding lead in the season points standings, she held on to Friday’s track record-breaking run of 6.523 seconds at 212.63 mph.

That earned Enders-Stevens the second No. 1 spot of the season and eighth of her career.

“We’ve got a really consistent hot rod right now,” said Enders-Stevens, who will face No. 16 qualifier Travis Mazza in Sunday’s first round of eliminations. “We went up there and tried some things that we hope will work tomorrow. Consistency is what’s going to get it done.

“It’s an honor to be where I’m at. I have a new outlook and enjoy where I’m at. I feel good and confident this weekend.”

It’s known as “Carburetor Day” – or in its simplest term, just “Carb Day.”

But the final day of on-track action Friday at Indianapolis Motor Speedway before Sunday’s 102nd Running of the Indianapolis 500 is so much more.

Especially on NBCSN, which will have wall-to-wall live coverage starting Friday morning.

Here’s how Friday’s schedule breaks down:

11 a.m. ET: Carb Day kicks off with the final practice for Sunday’s Indy 500. The session will last one hour in length.

1:30 p.m. ET: We’ll have coverage of the annual IndyCar Pit Stop Challenge. Which teams have the best – and most importantly, fastest and accurate – pit crews? Team Penske has won 10 of the last 12, including the last two years edging out Schmidt Peterson Motorsports each time. Who can potentially beat them this year?
